A method of combining AC impedance and weak polarization technology to measure corrosion rate of metals is presented. Based on this method, an instrument, CMB-4510, has been developed.
The breakdown voltage, permittivity, crystal structure, composition, surface and refractive index of the thin films were studied by I-V, C-V, XRD, EDS, AFM and elliptical polarizationinstrument.
An instrument measuring the distributed polarization coupling in high birefringence polarization-maintaining fiber (PMF) is developed based on white light interferometry.
